RTH256 Mod 1 Exam NEURO, GBS, MG Flashcards
What is a common pulmonary sequence?
Aspirate
Core Pulmunal ( R side ❤ failure )
Central sleep apnea
Respiratory muscle weakness is associated with?
Ventilatory Insufficiency
Atelectasis and Hypoxemia
Neurological
Muscle weakness is associated with?
Neuromuscular disease
Orthopnea
dyspnea
Fatigue
Peripheral nerve disorders that cause respiratory muscle dysfunction may be caused by
Inflammatory process
vascular disorders
metabolic disorders
Where is the peripheral nerve located?
Peripheral nerves go from your spinal cord to your arms, hands, legs and feet.
what is the main function of the peripheral nerve?
s a network of 43 pairs of motor and sensory nerves that connect the brain and spinal cord (the central nervous system) to the entire human body. These nerves control the functions of sensation, movement and motor coordination.
Why do we use spirometry?
Because we can use the spirometry results and transfer them to the mechanical ventilator.
What is spirometry?
It s an assessment tool for MV
Incentive spirometry is used to
To evaluate the effects of diaphragmatic breathing exercises and flow and volume-oriented
How can we diagnose diaphragm paralysis?
PFT (pulmonary function test)
BGS results in?
Flaccid paralysis of the skeletal muscles
Loss of reflexes that result from peripheral nerve damage.
Severe cases of GBS may result in
VENTILATORY FAILURE due to paralysis of the diaphragm.
NERVES MAY demonstrates Demyelination, Inflammation, and Edema.
Major pathological, structural and ventilatory changes to the lungs are due to
Alveolar consolidation from atelectasis
what demographic is most likely to be affected by GBS?
Incidence is greater in people over the age of 50.
50-60% more common in white males.
What antibody is elevated with GBS?
( IgM ) Immunoglobulin M
Immunoglobulin M
is one of several isotypes of antibodies that are produced by vertebrates. IgM is the largest antibody, and it is the first antibody to appear in response to initial exposure to an antigen.
In regards to GBS campylobacter jejumi is associated with what bacteria? Not chickenpox
Mononucleosis
Measles and mumps NOT CHICKENPOX
Mycoplasm pneumonie
Chlamydia psittaci
Common noncardiopulmonary manisfistations
Ascending paralysis. ( Muscle weakness or loss of muscle function (paralysis) affects both sides of the body. In most cases, the muscle weakness starts in the legs and spreads to the arms. This is called ascending paralysis
What is the most common respiratory muscle affected with GBS?
Diaphragm
What is the functional spontaneous recovery?
Functional spontaneous recovery in about 90% of cases.
GBS is peripheral so the strip of what is no longer present?
Myelin sheath
common non cardiopulmonary manifestations associated with GBS?
Distal Paresthesia or dysesthesias ( numbness or tingling)
Back, Buttocks, Leg pain
Absence of reflux
Difficulty swallowing
Diagnosis of GBS is based on
Elevated protein levels in cerebral fluid ( Spinal fluid)
Abnormal electromyography EMG
ABG of Acute ventilator y Failure
PH: ⬇ below 7.35 CO2 ⬆ above 45 use monometer for Vital Capacity
Vital capacity is
the greatest volume of air that can be expelled from the lungs after taking the deepest possible breath. ⬇ less than -20ml/kg NIF ⬇ less than 2525cm H2O
Any pulmonary pt’s is susceptible
Pulmonary Thrombosis / Thromboembolism
Severe Treatment of GBS
plasmapheresis
Auscultating Pt with GBS, findings
Crackles wheeze Diminished crackles and Ronchi
GBS is part of what nerve dysfunction?
autonomic nervous dysfunction 2
GBS hart rate
Tachy and Brady Hypotension
This 1st stage of a critical event are going to have what kind of heart rate?
Tachy
PFT results on a GBS pt will always be
Restrictive
GBS always leads to Atelectasis because
Pt can’t take deep breaths, atelectasis show as opacity on CXR
